Common use of Experimental Setup Clause in Contracts

Experimental Setup. In order to evaluate the performance of Jam-X, we carry out experiments in two small-scale indoor testbeds deployed in office environments with USB-powered ▇▇▇▇▇. In the first testbed, we use JamLab, a tool for controlled interference generation [5] to evaluate the impact of interference in a real- istic and repeatable fashion. In JamLab, interference is either replayed from trace files that contain RSSI values recorded under interference, or from models of specific devices [5]. In particular, we use JamLab to emulate the interference ▇▇▇- terns produced by microwave ovens, by Bluetooth, and by Wi-Fi devices. In the latter case, the interference emulates a continuous file transfer. To avoid additional interference as much as possible, we carry out the experiments in this testbed during the night, when Wi-Fi activity in the office building is lowest. In the second testbed, we do not use JamLab, but we deliberately choose an 802.15.4 channel af- fected by interference, namely channel 18. On channel 18 there is Wi-Fi traffic and sometimes also interference from microwave ovens in a nearby kitchen. For the experiments, we use two ▇▇▇▇▇ S and R. Node S -25 dBm and 0 dBm. R replies to the message using the transmission power contained in the packet, i.e., the same one used by S. By using different transmission powers, we create different types of links for each handshake. Each packet is sent after a random interval in the order of tens of milliseconds, and nodes remain on the same channel for the whole duration of the experiment. Each experiment consists of several hundred thousand handshakes.
